In simplistic terms, an atom's electrons are held tot he atom because they are attracted to the positively charged nucleus. In larger atoms the electrons are farther away from that nucleus and there are usually more electrons in between, resulting in a weaker attraction.
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
to become stable
Metals are likely to make anions. So they lose electrons to get a positive charge. The other elements gain electrons and get negatively charged.
Yes. Metals have lower electronegativities than nonmetals, and they tend to have fewer than four valence electrons, so they are more likely to lose electrons in order to achieve a noble gas configuration and become stable.
it causes the atoms to lose their negative electrons
Uranium loose electrons becoming a cation.
When atoms lose electrons cations are produced.
When atoms lose or gain electrons, they form ions. These are charged particles.
Metals lose electrons.
Atoms typically do not lose protons because that would change the identity of the element. Instead, atoms can lose or gain electrons to form ions with a different charge. Protons are not generally lost by atoms in chemical reactions.

No. Atoms of an element lose or gain electrons to form ions.
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Atoms that join by a covalent bond share electrons but do not gain or lose them. In a covalent bond, the electrons are shared between the atoms, creating a stable electron configuration for both atoms involved.
Yes. Metals have lower electronegativities than nonmetals, and they tend to have fewer than four valence electrons, so they are more likely to lose electrons in order to achieve a noble gas configuration and become stable.
